To all whom it concern.-

Be it known that I Onannnon W. TAYLOR,

a. citizen of the Unitedstates, residing at OakFa'rk, in the county ofCook and State of Illinois, have invented certain new and use I fulImprovements in Train Pipe Couplings,

the cars whether at rest or in motion; sec

of which the following is a specification. I My invention relates toimprovements in automatic train pipe-coupling, and the objects of imrovement are, first, to provide devices which .will readily var ouspositions and motions o the ends of nd, the provision of mechanism whichautomatically willopen the passe es connecting the fluid pipeswhen'thecoup ings are made and close such passages when the connections arebroken; and, third, the provision of means to prevent movement of thepipe cou 'ling' members relative to one another whi e in coupledposition.

Withthe above and other objects in view.

this invention consists of the novel features and the combinations andarrangement of parts here nafter more specifically described,

- illustrated in the drawings, and'particularly pointed out in theclaims ereunto appende In describing the invention in detail referenceis had to the accompanying drawings forming a part of this specificationwherein like numerals of reference indicate corresponding partsthroughout the several views,

- and in which Figure 1 is a side elevation of two C. B. couplers. withmy automatic coupling apparatus attached to the underside thereof ineac'h'in uncoupled position. 0

B. coupler. tion on line 4,-4 of Fig. 5.Fig. 5 is a front elevation of the pipe couplin member, and Fig. 6 is afront elevation o the hanger or ringportion of the depending bracket.

One embodiment of my invention will now be described.

t On reference to Figs. 1 and 2 it will be seen 7 that to the under sideof an M. C. B. coupler 8, I attach what I call a depending bracket whichconsists of the part 9, and the hanger or ring portion 10, the latterpreferably is made. in two parts or halves, each half having anupperflange 1 1- and a lower flange 14.

The part 9 is attached to the M. O. B. head old to the the pi 8 in thecommon way by bolts. The two parts of. hanger 10 are secured together byolts 13 in elongated openings 12 to the part 9,; and .at the lower endsof the two halvesby bolts 15 through flanges 14. The pipe coup- 'linmember, 16, shown is of the butttype .wit' the well known guide arms'17,18 and 19 for the usual urpose. 20 represents a con ling arm, as s ownit is disposed axially of tlie spring element composed of anextensionmember 2-1 and a compression member 22; The end plate or disk23 on the rear end of thec'ouplingarm is'sec'ured by bolts 24, and therearend of the extension member is secured to the disk 23bymeans of yokeand nuts 25. The forward end of the extension member is secured in likemanner on each side of the hanger or ring 10 as shown at 26 of Figs. 1,2, 3 and 6. On the front side of the hanger and behind the compressionmember 22 is an abutment collar 27 On the forward end of the couplingarm 20 is a pipecoupling member 16, which is provided with a rotatablevalve 28 with crank 29 and valve rod 30. This rod and looking rod 32 attheir 31 and 33 to permit of vertical and lateral movement. 34 denotesan aperture through c coupling to receive the locking bar carrio by anopposing pipe coupling men1- ber, and 35 indicates a like aperture inwhich rests the slidable'locking bar The usual gasket is shown by 36 andthe air hose by 37.

i The spring element preferably is composed of an extensions ring and acompression spring tandem.

butt type of pipe coupling member but my imiention is adapted to theside-port type as we 4 As shown in' Fig. 6, and by dotted lines in Figs.1 and 2 the front and rear of the opening through the hanger or ringportion 10 of the depending bracket is concave and the in.- ner' surfaceof the opening is convex to permit deflection of the coupling arm 20.The pipe coupling member may be increased in. dimensions to provideadditional ports and the rotatable valve made to regulate the flow offluid in each pipe. The description of my improvement as attached to oneM. C. B. coupler is a descriptionof both as each is a duplicate of theother. It will be apparent the coupling army has movement.,-throiigh therear ends are suitablyconnected to collar at he extension-member has aone end free. to permit radial deflection thereof. It Wll'l be noticed Ihave shown a ICC collar 27 is in slidable contact with the front ringportion of thedepiendin g bracket, and also may bedeflected in anydirection from' its horizontal axis. Tlie abutment outer face of thering. 10. The upper front surface of therin .10 is cut away suflicientlyto permit vertica movement 'of-the collar 27. The rear portion of theextension member 21 will tend notto be deflected excepting when I itisextended in coupling or while in coupled bar-is intended to preventmovement of the pipe coupling members relative to one an other while incon ledengagement and are automatically wit drawn' when the fearsseparate or become uncoupled. It is thought a mechanic will readilyassemble the respective parts and therefore no further description isgiven. In practice it is desirable to be able to adjust the hanger 10relativel to the car coupler, and this is possible by e ongated openings12 and bolts 13.

In operation when two cars approach each other for coupling of the carsthe guide arms 17, 18 and 19 will first engage and the faces of the pipecoupling members will contact in apositlon so the gasketswill registerand the apertures 34, 35 will register, then the extension member Willbe extended and the compression member will be compressed as eachcoupling arm is caused to move rearwardly through the hanger or ringportion 10 of the depending bracket andsimultaneously' the locking barand the valve mechanism will be operated, the former will be extendedinto the open aperture of the opposing. pipe coupling member and thelatter will berotated to open position, and vice versa are being uncouled;
